Description

BACKGROUND

[0001] 1. Technical Field

[0002] The disclosure generally relates to cooling systems for electronic devices.

[0003] 2. Description of Related Art

[0004] In an electronic device, such as a server, there are many electronic components which generate heat when the electronic device operates. In designing a electronic device, cooling systems are employed to dissipate heat generated by the electronic components to prevent the electronic components from failure from overheating.

[0005] A typical cooling system includes an air conducting cover defining an airflow channel, a fan and electronic components mounted in the airflow channel. The fan is configured to draw air into the airflow channel and force air past the electronic components which are cooled accordingly. However, with increased functionality, the number of electronic components increases beyond the cooling capability of the airflow channel. Some electronic components must be located outside of the airflow channel and require additional fans to cool them. As a result, power consumption of the electronic device increases and the additional fans will generate considerable noise during operation.

[0006] Therefore, there is room for improvement within the art.

DETAILED DESCRIPTION

[0013] Referring to FIG. 1 and FIG. 2, a electronic device 100 includes a chassis 10, a plurality of first electronic components (not shown), a plurality of second electronic components 40 and a cooling system 15. The first electronic components, the second electronic components 40 and the cooling system 15, are all mounted in the chassis 10.

[0014] The cooling system 15 includes an air conducting cover 20 and a fan set 30. The air conducting cover 20 is mounted in the chassis 10, and includes two sidewalls 222 and a wall 26 connecting the two sidewalls 222, from an area adjacent the center of their respective inwardly facing wall surfaces. The sidewalls 222 and the wall 26 cooperatively form a first airflow channel 22 at one side of the wall 26 and an opposite second airflow channel 24 at an opposite side of the wall 26. The first airflow channel 22 further includes a first air inlet 224 and an opposite first air outlet 226, respectively located at opposite ends of the first airflow channel 22 and communicating with the first airflow channel 22. The second airflow channel 24 further includes a second air inlet 244 and an opposite second air outlet 246, respectively located at opposite ends of the second airflow channel 24 communicating with the second airflow channel 24. The air conducting cover 20 may further include a first partition board 228 extending substantially the length of the air conducting cover 20 from the first air inlet 224 to the first air outlet 226 and located in the first airflow channel 22, dividing the first airflow channel 22 into two channels. The air conducting cover 20 may further includes a second partition board 248 extending substantially the length of the air conducting cover 20 from the second air inlet 244 to the second air outlet 246 and located in the second airflow channel 24, dividing the second airflow channel 24 into two.

[0015] Referring to FIG. 3, the fan 30 mounted in the chassis 10 is simultaneously aligned with the first air inlet 224 and the second air inlet 244. The first electronic components are located in the first airflow channel 22, and the second electronic components are located in the second airflow channel 24.

[0016] Referring to FIGS. 3 and 4, in operation, airflow from fan 30 simultaneously travels through the first airflow channel 22 and the second airflow channel 24 respectively from the first air inlet 224 and the second air inlet 244, and then out of the chassis 10 correspondingly via the first air outlet 226 and the second air outlet 246 so that the first electronic components and the second electronic components 40 are simultaneously cooled. Thus, fewer fans 30 are required due to the presence of both the first airflow channel 22 and the second airflow channel 24.

[0017] It is to be understood, however, that even through numerous characteristics and advantages of the disclosure have been set forth in the foregoing description, together with details of the system and function of the disclosure, the disclosure is illustrative only, and changes may be made in detail, especially in matters of shape, size, and arrangement of parts within the principles of the disclosure to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
